Hunting for Extraterrestrial Signals in the Milky Way's Center

The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) project, a collaborative SETI project led by Cornell graduate student Akshay Suresh, has been searching for technosignatures at the center of the Milky Way using a proprietary algorithm and data obtained by the Greenbank Observatory. The team was looking for regularly-spaced sequences of pulses across a signal range of a few kilohertz, similar to radar communications, but did not find any clear indications of periodic radio signals. However, the search accomplished several firsts and established constraints that future studies can build on.
